Adrienne McElwain possesses a passion for rocks that would make the Fantastic Four’s The Thing blush. McElwain credits her deep love for rocks to her father’s rock shop. “I’ve worked with rocks ever since my ninth birthday, so I have a 30-year history with geology,” she says. “In 2018, when our physical storefront closed down, I made it my personal goal to dig in mines all over the world and collect [rocks]. Since then, I’ve been to more than 40 countries and all seven continents, collecting, filming and discussing the different aspects of the local rocks and minerals wherever I go.”

Utah is a rockhound’s dream, but McElwain’s favorite local rock is the Rainbow Chert found in Caineville. “Tumbling that variation of chert produced something like an optical illusion, where the end result was matte in its appearance but felt glossy like a typical tumbled stone — so the look never matched the feel of the rock, and it was like my eyes couldn’t focus on it properly.”

McElwain’s love for minerals is rivaled only by her passion for ethically sourced, small-batch roasted coffee beans. “For our Meteorite blend, an Argentinian dark roast, we add a small meteorite sample from Campo del Cielo, Argentina in a little specimen bag,” she says. “That’s the whole idea behind Crystal Beans Coffee: You get a special blend of coffee with a rock or mineral sourced from the country of the beans.” Find out more at the DIY Fest and online at crystalbarista.com!
